Laravel 10 Image Validation Rule Example

Hello Guys,

This tutorial will give you an example of laravel 10 image validation rules. I explained simply about laravel 10 image validation. We will use laravel 10 image validation size. This article goes in detailed on laravel 10 image validation mimes. Let’s see below example laravel 10 validation image width and height.

Laravel 10 provides list of default image validation rules to prevent user.

image
mimes
dimensions
max

using above validation rules you can set file type like “jpg,png,jpeg,gif,svg”, using max you can set limit of file size. using dimensions you can set file height and width limit. so, let’s see the following simple example code:

Step 1: Install Laravel 10 App

This step is not required; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Create Controller

In this step, we will create a new ImageController; in this file, we will add two method index() and store() for render view and store image logic.

Let’s create ImageController by following command:

php artisan make:controller ImageController

next, let’s update the following code to Controller File.

app/Http/Controllers/ImageController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
  
class ImageController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(): View
    {
        return view('imageUpload');
    }
        
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request): RedirectResponse
    {
        $this->validate($request, [
            'image' => ['required',
                        'image',
                        'mimes:jpg,png,jpeg,gif,svg',
                        'dimensions:min_width=100,min_height=100,max_width=1000,max_height=1000',
                        'max:2048'],
        ]);
        
        $imageName = time().'.'.$request->image->extension();  
         
        $request->image->move(public_path('images'), $imageName);
      
        /* 
            Write Code Here for
            Store $imageName name in DATABASE from HERE 
        */
        
        return back()
                    ->with('success', 'You have successfully upload image.')
                    ->with('image', $imageName); 
    }
}

Step 3: Create and Add Routes

Furthermore, open routes/web.php file and add the routes to manage GET and POST requests for render view and store image logic.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\ImageController;
  
/* 
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::controller(ImageController::class)->group(function(){
    Route::get('image-upload', 'index');
    Route::post('image-upload', 'store')->name('image.store');
});

Step 4: Create Blade File

At last step we need to create imageUpload.blade.php file and in this file we will create form with file input button. So copy bellow and put on that file.

resources/views/imageUpload.blade.php

        <div class="alert alert-success alert-block">

                <strong>{{ $message }}</strong>
        </div>
        <img src="images/{{ Session::get('image') }}">
        @endif
      
        <form action="{{ route('image.store') }}" method="POST" enctype="multipart/form-data">
            @csrf
  
            <div class="mb-3">
                <label class="form-label" for="inputImage">Image:</label>
                <input 
                    type="file" 
                    name="image" 
                    id="inputImage"
                    class="form-control @error('image') is-invalid @enderror">
  
                @error('image')
                    <span class="text-danger">{{ $message }}</span>
                @enderror
            </div>
   
            <div class="mb-3">
                <button type="submit" class="btn btn-success">Upload</button>
            </div>
       
        </form>
      
      </div>
    </div>
</div>
</body>
    
</html>
